The Blue Heaven power cord seems like a conventional, three-core AC cord, but don't be fooled.

The flagship M6 offers the best performance and utilises three hybrid MainsARAYs fitted in parallel (rather than in series) to the bus bars, removing high-frequency noise whilst remaining outside of the circuit. Rather than being star-wired (which is susceptible to RFI), the wiring is run along three bus bars which are all isolated from each other. The earth bus bar is kept as far away as possible from both the live and neutral.
